Laureate™ Dual-Channel Pulse Input Totalizer

With Two Independently Scalable Input Channels & Presets
Navigation:  Home > Electronic Counters
Totalizer - electronic counter by Laurel Electronics
Key Features
  • Independent, scalable totals for Channels A & B.
  • Totals stored in non-volatile memory.
  • Inputs from NPN or PNP proximity switches, contact closures, digital logic, magnetic pickups down to 12 mV, or AC inputs up to 250 Vac.
  • Up counting from zero to preset value using positive scale factor.
  • Down counting from preset to zero using negative scale factor.
